Controllers are essential personnel in the business world, responsible for providing oversight to an organization’s business operations. A controller must have strong analytical abilities, problem-solving skills, and experience in financial reporting, budgeting and forecasting. They need to possess a comprehensive understanding of accounting principles and regulations, as well as industry-specific knowledge. The highest qualification demanded from controllers is their certification from the Institute of Certified Management Accountants (CMAs). This certification requires candidates to pass two exams and undergo lengthy training programs with special attention on areas like strategic management and finance analytics. Furthermore, certified controllers must also complete optional continuing education programs to stay updated with the latest trends. With these qualifications, controllers can serve as reliable decision makers and leaders, who can drive an organization to success.
